<P>PROBLEM TO BE SOLVED: To provide a composite material having a low cost, excellent conductivity, and high corrosion resistance, its manufacturing method, and a fuel cell having excellent durability. <P>SOLUTION: This composite material has a structure wherein a coat 3 comprising conductive graphite is formed directly on the surface of a metallic substrate 20. Such material can be manufactured by forcibly transferring the graphite 60 blown off by spattering to the metallic substrate 2 by the flow 50 of an inactive gas and by making it adhere to the surface of the substrate. This fuel cell is structured by using the composite metallic material obtained this way for a separator. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
